中間表
@Entity
@Table(name = "T_TEACHERSTUDENT")
@SequenceGenerator(name = "SEQ_TEACHERSTUDENT", sequenceName = "SEQ_TEACHERSTUDENT")
public class TeacherStudent implements Serializable {
private Long id;
private Student2 student;
private Teacher2 teacher;
private String note1;
private String note2;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_TEACHERSTUDENT")
@Column(name = "ID", nullable = false, precision = 22, scale = 0)
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
@Column(name = "note1")
public String getNote1() {
return note1;
}
public void setNote1(String note1) {
this.note1 = note1;
}
@Column(name = "note2")
public String getNote2() {
return note2;
}
public void setNote2(String note2) {
this.note2 = note2;
}
@ManyToOne(cascade=CascadeType.ALL)
@JoinColumn(name = "student_id", unique = true)
public Student2 getStudent() {
return student;
}
public void setStudent(Student2 student) {
this.student = student;
}
@ManyToOne
@JoinColumn(name = "teacher_id", unique = true)
public Teacher2 getTeacher() {
return teacher;
}
public void setTeacher(Teacher2 teacher) {
this.teacher = teacher;
}
}
hibernate.cfg.xml 引入對象
<mapping class="com.dvn.li.model.Student2"/>
<mapping class="com.dvn.li.model.Teacher2"/>
<mapping class="com.dvn.li.model.TeacherStudent"/>
測試：
SessionFactory sessionFactory = null;
Session session = null;
try {
sessionFactory = HibernateUtil.getSessionFactory();
session = sessionFactory.getCurrentSession();
session.beginTransaction();
Student2 s = new Student2();
s.setName("小豬");
Teacher2 t = new Teacher2();
t.setName("小李");
TeacherStudent ts=new TeacherStudent();
ts.setStudent(s);
ts.setTeacher(t);
ts.setNote1("以呀呀！！！");
session.save(s);
session.save(t);
session.save(ts);
session.getTransaction().commit();
} catch (Exception e) {
if (session != null) {
session.getTransaction().rollback();
}
}
測試通過！
如果自己做測試，可以通過SchemaExport導入表結構
SchemaExport export = new SchemaExport(new AnnotationConfiguration()
.configure());
export.create(true, true);
